Wilson Phillips singer Carnie Wilson famously underwent gastric bypass surgery and now she has publicly announced she’s been diagnosed with Bell’s palsy, a nerve disorder that causes paralysis, usually temporarily, on one side of the face.

On March 14 the 44-year-old tweeted to her 5,000 followers about her diagnosis:

“Just wanted you all 2 know that I have Bell's Palsy on lf side of face right now. Scary, unfortunate, but it goes away. A challenge! Love u.”

The first time Wilson opened up about her medical struggles was in 1999 when she chose to undergo surgery to help her lose more than 150 pounds.

Keeping her fans up to date on her condition, she took to her Twitter page the day after her recent announcement:

“Feeling love from Ya'll. Love you all back. I am listening to Frank Sinatra. Really calming”

Wilson felt compelled to share the news about her diagnosis with her fans and she explained in a statement to TV Guide why:

"I just said, 'This is what's happening in my life, and I'm not going to hide anything.' I wanted it to be real," she told TVGuide.com. "It's what I'm going through. It's what a lot of people need to see because they've trusted me to be open with them. It's like a responsibility for me."

Wilson also told her fans she once had Bell’s Palsy on the right side of her face, but that it went away, adding that  acupuncture was helping her feel better.

The “Hold On” singer continues to thank her fans on Twitter for their support.

According to the Mayo Clinic, it’s not certain what causes Bell’s palsy but a viral infection is suspected.

Actors like George Clooney and Pierce Brosnan had the disorder as children, the Huffington Post reported, but have since made full recoveries.

After stuggling with her weight for years and even undergoing a second weight-loss surgery in 2012, Wilson told People magazine learning to love herself has been a struggle.

"I'm not striving for perfection. This has to be for the rest of my life," she told the magazine.

"I tell my daughters, 'You have to love yourself,'" she continued. "If I ever hear them put themselves down I tell them, 'Don’t say that. You have to say positive things about yourself because you are what you think you are.' For me, I know I don't weigh 120 pounds, but I’m also not 500 pounds. I am who I am and I celebrate where I am when I'm there."
